Abstract

Disclosed is a method and apparatus for amplitude modulation of an RF transmit signal using pulse width modulation to control an amount of energy within each period. The apparatus includes a signal processing circuit with an input port for receiving of information indicative of a carrier frequency and modulation data. The signal processing circuit has a first output port and a second output port for providing of output signals having a phase relationship therebetween. A power amplifier is provided for receiving the output signals and for generating a pulse width modulated signal in dependence thereon.
